The only known information about this creature is from its brief apperance in EP072. It seems to be a bear, possibly a scrapped version of Teddiursa, Ursaring, or Honōguma. Although the artifact has brown markings, since all theotherPokémopolisPokémon seen in the episode had similar markings, it is unlikely that this would be a normal feature. Whether or not it was even intended to be in the games is unknown.
Unnamed arachnid
This creature made its sole apperance in EP138. It seems to be a giant yellow spider, with four red compoundeyes, and a mouth with four large fangs. It has a thorax with eight long brown legs. Its abdomen is much larger relative to the rest of it body, with two thin black stripes. Its cry has the sound of a scream, not unlike Victreebel's. The nature of it appearance (in a Gligarman movie) would appear to indicate it may be a fictional monster or Pokémon, and whether it is supposed to be portrayed by a real Pokémon, a mecha, or simply special effects is unclear, though its movements and its cry give it an extremely organic appearance. Due to its appearance rather early into the Johto series of the anime, it is unlikely to have been intended to be in the games, and can be considered to be an anime-exclusive Pokémon.
